To all whom it may concern Be it ltnown that l, iii-termini lt nms BUR- NETT, residing at the city oi. Montreal, Pro-viiice of Quebec, Dominion of (Jun-eds, a citizen of the United States or i miericn have invented certain new and useful improvements in Convertible Flat and Hopper liottom Dumping Cars; and l do hereby declare that the following is a full, clear, and exact description thereoli My invention relates particularly to cars to]? carrying loose commodities such 215 grain, coal, gravel, and the like, and it has for its object to simplify the construction of the car as s. cnrrier for loose commodities, to simplify the coi'istruetion oil the hoppers of cars of this type and render more oiled tive the joint between the adjustable floor parts of the car and the mouths of the hoppers.

lily invention may be said to consist of the construction, combination and particular orrangement of parts hereinafter described and pointed out in the claims.

l? or iiullcoinprehension, however, of my invention, reference must be had to accompanying drawings forming; u part of this specification in which similar reference characters indicate the some parts, and wherein:

Figure l illustrates diegreminziticelly a, transverse Vertical sectional View of a convertible cur containing my invention, with the ports orrunged for service as :1 general freight-carrier; F 2 is or similar view to Fig. l oi one half only of the cur, however, and drawn to at larger scale, the parts being; arranged for service e general freight carrier, and shown in dotted lines as orrsn ed tor agrein carrier; and Fig. 3 is a detail. perspective View of the parts of the combined floor and grain door and the position oi the fixed floor with which it is in hinged relation My improved car has :1 pair of hoppers disposed transversely and each consisting of s pair of vertical walls 2, 2, and a fixed inclined floor member, the latter being formed by the end portions of a plate member ex tending transversely to within comparetively close proximity to the sides of the car, the middle of this member resting on the centersill end being shaped to present oppositely facing angular door jombs i, at. lit consists, preferably, of or non" oil plates 5,

'li conmitutin'g themed-floormembers or" the hoppers and the door-ja1nb portion is proferubly tor-med oi a separate metal plate (3 bent to the form required, the edges oi all three plates being riveted together end to the center sill us at 7. The end edges of these inclined lice-r members are attached to the bottom edges or the vertical side walls 2 2, thus lt'orming chutes, the discharge mouths of which are disposed in angular positions slightly removed from the perpendicular plane oi the sides of the cur. lleletivelv small doors 12 close the mouths of these chutes, and, like these months ill'l), when closed, in position inclined only slightly from the vertical. it serious detect in cars of this type has been the n'lisfit of the floor members and the unavailability of the groin doors when required. it overcome these defects by providing a displuceeble telescopic floor member adopted to displace any groin and the like left on the center sill or other members of the under frame on which these displuceuble floor members rest. The specific device for the PUPIX'SQ comprises a member made up of tongue-andgroove boards arranged longitiulinelly with relation to the car, and iustmied together by metal bands on ruiposite sides of this door menilber and braced by a. series of ungledrons 61, halt the length oi each of which is riveted in place and the remainder sprung out slightly as at ('32 to accommodate the extensible member to be presently further elluded to. T his door member is hinged to the fixed floor members 63 of the car by means of trunnions 65 fastened to the door by plates 66 to which they are welded, such plates beingriveted or be: .ed in place, and :1 plate 67 of half lJ-Itorm with its angle disposed so as to bear on the top of the side sill and against a threshold strip 68 when the member 60 is raised and thus not as a grain seal, and, at the same time, serve as :i stop limiting the outward movement there ot' and taking up some of the stress which would otherwise be carried entirely by the door frame in the side of the car. The trunnions are journaled in sockets beneath the contiguous edges of the fixed floor me1nbcrs in which are mounted oilset plates 70 confining the trunnions between them, the side of the car-body and the top of the side sill. The fixed floor members are securely fastened in place by being bolted or rivetedto the underfroming. The tree edges or these members 60 are beveled to coincide Elli lot

and make Contact with the diagonal iambs 4, 4, on the center sill.

What I claim is as follows:

1. In a car for loose commodities, the combination with a side'sill and center-sill, of a discharge hopper comprising vertical Walls hung from the car body, a diagonal hopper floor member carried by theW-alls and extending substantially the full length and Width of the hopper, such diagonal floor member consisting of a pair of parts constituting the floors of the respective hoppers and a central part uniting the said floor parts and having an angular rib presenting opposite diagonal door-jambs and a pair of combined fioor members and grain-doors hinged contiguous to the sides of the car and having beveled free edges for engagement with the door-jambs.

2. In a convertible car the combination With the under framing and body, of a pair of combined floor and grain-door members hinged contiguous to the sides of the car and collectively extending from side to side of the car, discharging hoppers beneath the floor having diagonal fixed floors consisting of a member extending transversely of the car and including an angular middle part eena extending longitudinally of the car and mounted on the under framing, the said part presenting oppositely inclined door-jambs for engagement by the combined floor and grain-door members.

8. In a convertible car the combination with the under-framing and body, of a pair of extensible combined floor and grain-door mei bers hinged contiguous to the sides of the car and collectively extending from side to side of the car, discharging hoppers beneath the floor having diagonal fixed floors consisting of a member extending transversely of the car and including an angular middle part extending longitudinally of the car and mounted on the under framing the said part presenting oppositely inclined door-jambs for engagement by the combined floor and grain-door members.

In testimony whereof l have signed my name to this specification in the presence of two witnesses.
